This is proposed in Publication No. 57869.

On the other hand, in an elevator control device having a non-stop floor registration means that registers a pre-specified floor as a non-stop floor and allows the car to pass through the non-stop floor during normal operation, it is possible to During operation, it is necessary for the safe operation of the elevator that the registration of non-stop floors is canceled so that the car can stop at any floor.

Therefore, in the elevator control device proposed in the above-mentioned conventional technology, during emergency operation, the registration of non-stop floors is canceled, and when a forced stop command is issued and the car stops at the non-stop floor, the car door is opened and the car door is opened. The structure is such that the prohibition of hall call registration for non-stop floors is lifted.

For this reason, in the elevator control device proposed in the above-mentioned prior art, passengers can get off to a non-stopping floor from a car that has stopped on a non-stopping floor during an emergency operation. In addition, passengers who get off at a non-stopping floor can register their car by operating the hall call button of that non-stopping floor as necessary to register the car and call the elevator car on the non-stopping floor. You won't be stuck in the hall.

<Problems to be Solved by the Invention> In the elevator control device proposed in the above-mentioned prior art, a forced stop command is issued during emergency operation, and a floor registered as a non-stop floor by the non-stop floor registration means is When the car stops and the car door is opened, the prohibition on registration of landing calls for the non-stopping floor is lifted.

Therefore, even if there are no passengers in the car or if a passenger does not get off the car even if the car door opens, the ban on passenger call registration for non-stop floors where the car stopped may be lifted even though it is not necessary. In order to be
It may not be possible to quickly respond to calls for floors other than the non-stop floors, which may impede the efficient operation of the elevator.

The present invention was made in view of the current status of this type of elevator control device as described above, and its purpose is to control the elevator control system based on the condition of the passengers in the car when stopping at a non-stop floor during emergency operation. To provide an elevator control device capable of realizing efficient elevator operation by canceling the prohibition of hall call registration for non-stop floors only when necessary.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention registers a floor specified in advance as a non-stop floor, and registers a non-stop floor in which a car passes through the non-stop floor during normal operation. In an elevator control device having means,
If the car stops at the non-stop floor during emergency operation,
an in-car passenger detection means that detects that a passenger has alighted from the car and issues a detection signal; The present invention is configured to include a recovery means for canceling the registration by the floor registration means and validating the hall call registration of the non-stop floor.

<Operation> In the present invention, when a forced stop command is issued during emergency operation and the car stops at a non-stop floor, the in-car passenger detection means detects that a passenger has alighted from the car and issues a detection signal. Only then, the prohibition of hall call registration for the non-stop floor is canceled by the recovery means, and the hall call registration becomes valid.

In this way, if there are no passengers in the car or if the passenger does not get off at the non-stop floor where the car stopped, unnecessary recovery of hall call registration is not performed.

The operation of the embodiment of the present invention configured as described above is as follows.
This will be explained next.

In FIG. 1, when the non-stop floor registration switch NS is operated, the power supply voltage is applied to the non-stop floor registration relay A, so the non-stop floor registration relay A is energized and the contact _A1 is turned ON. Also, since the non-stop floor registration relay A is energized, the contact point in Figure 2 is
A ₂ and A ₃ are turned OFF.

In this way, by operating the non-stop floor registration switch NS, contacts A ₂ and A ₃ are turned OFF, so even if you operate the hall up call button 2U or the hall down call button 2D on the second floor. , landing up call registration relay 72U or landing down call registration relay 82D
is not registered, and the second floor is registered as a non-stop floor.

Therefore, during normal operation, the elevator does not stop at the second floor, and the elevator operates in such a way that the car passes through the second floor.

For example, during an emergency operation such as an earthquake control operation, when a forced stop command is issued and the car stops on the second floor, the car door opens, allowing passengers to get off to the second floor, which is a floor that does not stop during normal operation.

When a passenger alights from the car, a car load detection relay (not shown) detects that the car load has changed to a lighter load direction and operates by connecting contacts _W1 and _W2.
turns on.

Also, at this time, the car is stopped on the second floor, so
Contact _2F3 is turned on by the elevator car position detection relay.

Therefore, power terminal P, contact A ₁ , contact W ₁ , contact 2F ₃ , in-car passenger detection relay B, and power terminal N
A closed circuit is formed, the in-car passenger detection relay B is energized, and contacts B ₁ , B ₂ , and B ₃ are turned ON.

In this way, contact B ₂ and contact B ₃ are turned on, so when you operate the hall up call button 2U on the second floor, the power terminal P, the hall up call button 2U, contact B ₃ ,
Switching contact 2F ₅ , landing up call registration relay 72U
A closed circuit is formed between the power terminal N and the power supply terminal N, and the hall up call registration relay 72U is energized.

Similarly, when the hall descending call button 2D is operated on the second floor, a closed circuit is formed by the power terminal P, the hall descending call button 2D, the contact B ₂ , the switching contact 2F ₆ , the hall descending call registration relay 82D, and the power terminal N. Then, the hall down call registration relay 82D is energized.

As described above, when the hall up call registration relay 72U is energized, the contact _72U1 is turned ON, the hall up call registration relay 72U is self-held, and the hall down call registration relay 82D is energized. Then, the contact point _82D1 is turned on, and the hall descending call registration relay 82D is self-held.

On the other hand, when the elevator operates and the car moves from the second floor, an operation detection relay (not shown) is energized, so the contact _U1 turns ON, and the car passenger detection relay B becomes self-held.

Therefore, as mentioned above, a passenger who gets off on the second floor, which is a non-stop floor during normal operation, can call the car to the second floor by operating the landing down call button 2D or the landing up call button 2U on the second floor. is possible.

In addition, while the car is stopped on the second floor, the normally open switching contacts 2F ₅ and 2F ₆ are ON, so the landing call up call button 2U can be activated by operating the landing call down call button 2D. HOD or HOD
By energizing the car and opening the previously closed door, passengers can board the car before it leaves the second-floor landing area.

In this way, it is possible to prevent an accident in which passengers who have gotten off to a floor that is considered a non-stop floor during normal operation during emergency operation are trapped in the landing hall of that floor.

As mentioned above, during emergency operation, if there are no passengers in the car that arrives at the second floor, which is a non-stop floor during normal operation, or if no passenger gets off the car, a load detection relay (not shown) is activated. Contacts W ₁ and W ₂ remain OFF because they do not operate,
In-car passenger detection relay B is not energized.

Therefore, in this case, the second floor hall call registration is not validated, and the second floor hall call registration remains invalid. In this way, the registration of a hall call for the second floor of a floor that does not stop is valid only when the passenger gets off to the second floor, and it will not be invalidated unnecessarily. It is possible to respond quickly and improve elevator operation efficiency.

In the embodiment, the in-car passenger detection relay is energized by the activation of the car load detection relay, which is activated when it is detected that the car load has changed to a light load direction. However, the in-car passenger detection relay of the present invention is not limited to the embodiment. A switch is provided on the floor of the car or on the floor of the non-stop floor, and when the switch is operated by a passenger's foot, the relay is turned on. Various types of sensors can be used, including those that detect passengers photoelectrically or using ultrasonic waves.

Furthermore, in the embodiment, a case has been described in which an elevator operates between three floors and the second floor is a non-stop floor. It can be applied when the floor (m≦n-2) is a non-stop floor.

<Effects of the Invention> As explained in detail above, according to the present invention, only when a passenger gets off on a non-stop floor that stopped during an emergency operation, the recovery means is activated and the landing call registration for that non-stop floor is activated. It is an object of the present invention to provide an elevator control device that can improve elevator operation efficiency by preventing passengers from being trapped in a landing hall and preventing hall call registration from becoming valid unnecessarily. I can do it.
